Short bus preschoolers could have formulated a more legitimate poll. I don't set a high bar for sports page writers, but the guy who picked this up and wrote an article around it should really be forced to have his dick concussed by J.J. Watt.
The poll provided options and asked respondents to answer "yes" or "no" to them. This type of poll is among the worst, and no survey looking to produce reliable, "scientific", results utilizes this tactic. Unfortunately people are dumb as shit, and it's equivalent to leading a witness.
Exacerbating this is the fact that the poll did not ask respondents to indicate if THEY had curbed their viewership, and if so, what motivated THEM to do so. It asked every participant of the survey to speculate on what they BELIEVED was causing the drop, whether they had stopped watching or not. You would expect the results to skew towards a story that was discussed on every news and major sporting event broadcast in the month of September whether it had anything to do with it or not.
If I had to guess, Colin Kaepernick's first start this season probably saw a massive ratings boost, not a decline. A small percentage of people who like what he's done would be more likely to tune in and hope to watch him succeed. A large minority would tune in to hopefully watch him fail in spectacular fashion, and a massive majority wouldn't modify their behavior either way.
It's too bad also, because the way police in this country do their job (and are trained to do their job), deserves to have every player, coach, and fan in the stands on their knees in protest. But with every news broadcast and idiotic NFL protest player suggesting the atrocious policing is all a result of widespread institutional racism, the actual problem is going to persist unchecked for decades more.
